Ref: the LEOSA, there is an outfit out of NJ made up of lawyers and cops that go around the country educating departments and officers (retired and otherwise) on the LEOSA.
Sheepdog Academy. Their website offers education material and court cases. No City or State has faired very well in violating the rights under the LEOSA.
I'm not sure, but it would seem to me if HR 882 passed local departments would find themselves in the same boat.
